P2P流量识别技术研究

随着P2P技术的广泛使用，P2P应用虽然丰富了人们的生活，但部分P2P应用严重的影响了企事业单位的正常办公，并且为不良信息的广泛传播提供了便利。如何有效的识别并控制P2P流量已成为当前Internet技术中越来越重要一项研究，本文对P2P流量的识别进行了深入的研究，并提出了字段特征与PDU格式两种有效的识别方法。

Research on P2PTraffic Identification Technology

With the P2P technology widely used,although P2P applications enriches people＇s live,but part of P2P applications effect normal office of enterprises,and offers facilities for bad information widely spread.How to identify and control the P2P traffic has became an increasingly important research in internet technology,this paper make series of studies about P2P traffic identification,and comes up with two ways which is signature strings and PDU format about how to identify the P2P traffic.
